RY, MAINE, A COR- POWER-BRAKE.

SPECIFICATION forming part of Letters Patent No. 786,379, dated April 4, 1905. Application filed July 13, 1904. Serial No. 216,339.

To all whom, it 777/f!/ 7/ concern:

Be it known that I, LOUIS PFINGS'I, of Bos-' ton, in the county of Suffolk and State of M assachusetts, have invented certain new and useful Improvements in Power-Brakes, of which the following is a specification.

My invention relates to new and useful improvements in either mechanical hand and electric power combined or capable of opera-' tion independently of one another, and especially to brakes which are applied by power from an electric motor transmitting its power through a train of gears to a chain-winding spindle of vehicles or cars.

The object of this invention is to rotate the brake-spindle of a vehicle or car by electric power through clutch mechanism and compound gearing, combined with brake-handle capable of being operated separately or together--that is, the spindle can be operated by power without operating the handle either to its right or left rotation, or the spindle can be operated by hand-power in either direction without moving any of the electrical apparatus, or the spindle can be rotated by motor and hand power simultaneously for the winding or unwinding of the chain around the spindle when applying or releasing the brakes.

Another object of my invention is to compound the power of the motor through a train of gears to the upright brake-spindle; and a further object is to partially apply the brakes through clutch mechanism without using all of the power that the motor possesses when running and with the circuit fully cut in.

These and other objects are accomplished by mechanism shown and hereinafter described. My invention consists of certain novel features hereinafter described, and particularly.

pointed out in the claims.

In the accompanying drawings, which illustrate a construction embodying my invention, 1 Figure 1 1s a side elevation of part of a car showing the location of the improved hand and motor geared brake-spindle when not in operation with the shoes not applied to the wheels. Fig. 2 is a top plan View with the body of the car removed and showing the motor-geared driven brake-spindle located on the platform of the car and also the brakelever mechanism with the shoes not applied. Fig. 3 is a sectional elevation of the baseframe, motor-frame, and extension-frame clutch mechanism, gears, ratchet-wheel, the hub, with the brake-spindle in full lines, and the portable loose revoluble handle partly in section. Fig. 4 is a sectional elevation of the base-frame, motor-poles, motor-frame, bedplate, and portable extension frame, with brush-arms, brake-insulating washers, the armature, shaft-spindle, clutch mechanism, and foot-lever in full lines. Fig. 5 is a longitudinal sectional view on the line X X, Fig. 3. Fig. 6 is a longitudinal sectional View on the line X X, Fig. 3. Fig. 7 is a longitudinal sectional view on the line X X*, Fig. 3.

Like letters of reference refer to like parts throughout the several views.

The bed-plate A is bolted to the platform buffer-timber a of the car, and secured to said bed-plate A by suitable bolts is the base-frame or motor-support B.

B and B" are brackets forming a support for the lever-fulcrum at B.

B is an opening formed in the base-frame or motor-support to admit the lever for the operation of the clutch.

On the bed-plate A there is provided at its center a boss A to form a guide or bearing for the lower end of the motor journal-shaft J and adjacent thereto there is also a hearing to support and guide the brake-spindle M a A'.

A represents ribs formed on the top side of the bed-plate, connecting with the boss A.

A* and A are openings in the bed-plate to admit of the electric conductors.

A represents bolt-holes and bolts passing through flange Bof the base-frame B, thence through the bed-plate A and buffer-timber (0 and secured thereto.

B is a lever-spring todisengage the clutch members.

B and B are bolts to attach spring B to the frame B.

B and B are rivets passing through the frame B, also through the insulating-pieces B and B to hold fast the contact-plates B and B.

B is a projection on the base-frame B forming a cavity B for the housing of the gear 1.

B forms a support for the motor-frame C.

B is an enlarged diameter of the motor base-frame B, forming a socket B for the insertion of the lower end of the motor-frame O.

B represents tapped bolts passing through the enlarged portion B, thence through the motor-frame C to the pole-pieces C, securing the same all in an assembled position.

D is the extension-frame, forming a housing or covering for the entire electric-motor apparatus.

D and D are covers for the hand-holes D and D, formed in the sides of the extensionframe D.

D represents bolt-holes to receive bolts to fasten the covers onto the extension-frame over the hand-holes D and D.

D is a boss formed on the under side of the top of the extension-frame D, forming the upper bearing at D for the armature-shaft J.

D and D are insulating-bushings for the purpose of insulating the brush-holding brackets D' D".'

D is a metal washer placed between the bushing D and jam-nut D". The nut D, meshing with the thread on the lower end of the boss D", is used for the purpose of fastening the brush-holding arrangement in a fixed position.

D and D are the brush-holding arms secured to the bracket D 1)". The brushes 1 and D make contact with the commutator J D is a boss on the top of the extensionframe D, forming a guide and bearing D for the upper end of the brake-spindle M.

D is an enlarged diameter of the extensionframc D, housing and passing over the upper end of the motor-frame (l.

D D are tapped bolts passing through the enlarged part of extension-frame D, through the motor-frame O, and securing the polepieces G, and thereby holding the upper portion of the apparatus in an assembled form.

J is the motor-armatu re with extended shaft ends forming journals J and J The lower journal J has a guide and step bearing A in the bed-plate A, and the upper journal end J" has a guide and bearing in the boss D" at D By this means the motor-armature is held in place whether the motor is in operation or not. On a portion of the lower armature journalshaft J there is fixed a driving clutch member J and below this member there is an idle or driven clutch member E, loosely surrounding and guided by the shaft J E is a pinion-gear that is a part of the driven clutch member E and is attached by the throat E.

E is a loose-fitting ring for the clutch member E, so that the two clutch members can be brought together.

F is the long end of a foot-lever.

F F is the short end bifurcated and bridged on its under side by the piece 1*. The lever F is fulcrumed on the pin F at B The pin is supported by the brackets B B G is an extension-arm pivoted loosely on the pin F and resting on the bridging-piece F and passing between the arms F F. The arm G at or near its center separates, forming two arms G G, uniting again at the rear, and from this portion there is a projecting piece G to which the insulating-bars G G are attached. These are to prevent the current from running into the other parts of the apparatus from the contact-finger G. The linger G is attached to the bars G G. On the double arm Gr G at its center there are holes to permit tapped bolts and G"entering and being screwed into each half of the clutch-ring E thereby forming a pair of trunnions, so that the clutch member E can be brought in contact with the clutch member J. On the spindle M and attached thereto is a ratchet-wheel H, resting on the bedplate A, and cooperating with said ratchetwheel H is a pawl H, pivoted on the pin H. The pawl H rests on the flange B of the baseframe. Above the ratchet-Wheel H there is a spur-gear 1, attached by the pin 2 passing through the hub of the gear and brake-spindle and also keyed by the key I. The gear 1 meshes in with the pinion E. At or near the top of the spindle M there is attached a hub M This hub and the projecting spindle M are housed over by the hub of thehandle N, formed by the chambers N and N. The hub M and the spindle M" support the handle N.

N is a bell-crank lever supported and pivoted on the pin N on the brackets N, formed on the handle N. There is also a tensionspring N interposed between the handle N and the bell-crank lever N On the lower end of the vertical arm of the bell-crank lever N there is attached and loosely connected at N" a reciprocating pin N, which passes through the opening N, formed in the walls of the hub of the handle and operated by the bell-crank. The pin Nweontinues and passes into openings M of the hub M. Just below the top of the spindle M there is an annular groove N to permit a pin to work loosely therein and prevent the displacement of the handle. This pin performs no function as to the operation of the handle and said handle may be operated without it. The pole-fields K are for the purpose of magnetizing the poles of the motor.

L is the section of the armature-winding on the line X X, Fig. 3, and L is the armaturecore.

The mode of operating the motor-geared brakespindle to set the brakes is as follows: First, the operation is to cut in the current starting the motor to run while the clutches are disengaged; second, to apply the brakes the operator engages, by the mechanical means of pressure or otherwise, the clutch members E and J with each other. This will rotate the pinion E, which meshes in with the gear 1 which is keyed to the spindle M, and by this.

means it will rotate the spindle M, winding up the chain M. During this operation in order to prevent the rotating of the handle N the operator disengages the pin N 7 from the hub M by the crank-handle N, at the same time holding the handle N. This will allow the rotating of the spindle M in the chambers N and i 2 of the handle N, thereby winding up the chain, pulling the brake-rod g, actuating the brake-lever I, thence pulling the rods land actuating the truck-levers m, thereby setting the brakes. I/Vhen the brake is sufficiently set, the motor clutch member E is disengaged from the member 1*, thereby cutting out all electric-motor power. During this operation the pin N is permitted to enter one of the openings M* in the hub M after which the brake is held when set either by the brake-handle N or by the ratchet-wheel H and the pawl H. To release the brakes, the operator disengages the ratchetwheel and pawl and the pin N from the hub M During this operation the operator has hold of thehandle N. The spindle will automatically unwind itself, rotating in the handle-chamber. At the same time the operator might release the handle N, allowing it to rotate with the ing any of the motor apparatus, the operator must disengage the clutches and turn the handle to the right, thus winding up the chain and setting the brakes. To release, there are two methods: first, to allow the handle to revolve with the spindle, or to disengage the pin N holding the handle still and allow.- ing the spindle to rotate in the handle-chamber. It does not follow by this construction that the motor must run continuously. It can be started to rotate just before the clutch member J and E are engaged, while operating the clutch-lever F.

As shown in Figs. 1 and 2, the construction of the platform and ear-bottom frame consists of buffer-timbers a with a platformflooring b. c c 0 c are the supporting-timbers, fastened to the body of the car and supporting the flooring b and buffer-timber a. (Z is the end sill, which is fastened to the ex- -usual manner of car-building.

treme end of the side sill e. f represents the bottom-frame cross-timbers, which are fastened to the side sill to support the flooring. To the end sill (Z and side sill c the end frame and side frame of the car are secured in the g is the main brake-rod, and at one end of said rod is connected the brake-chain M, and the other end is pivotally connected to the center brake-lever lb. The main or'center brake-lever lb is supported by the bracket 2', secured to the bottom of the car, and has a loose-motion slot j, and said brake-lever /b is held in place by the pin k. Pivotally connected to the main brake-lever it is the secondary brake-rod Z,

pivoted at its opposite end to the truck brakelever m, which is pivoted on the brake-beam 7). At the lower end of the brake-lever m is pivotally connected the brake-rod 0, which at its opposite end is connected to the truck-adjusted arm a. On the ends of the brake-beams p are fastened the brake-shoes g, which come in contact with the periphery of the wheels 1', mounted on the axle s. The brake-rod g and the secondary rod Z (shown on the right of Fig. 1 and Fig. 2) extend forward and are connected to similar mechanism at the righthand end of the car. The operation of this mechanism is as follows: By rotating the spindle M and winding up the chain Mthe brake-rod Q will be pulled forward, thereby actuating the brake-lever b. This will pull in the opposite direction the secondary rods lb, and by this operation the secondaryrods will pull the truck-levers m toward the center of the car, pressing out the bottom end of the levers m toward the end of the car, causing spindle with the brake-handle as hereinbefore described the spindle can revolve in either direction without rotating the handle, or the handle can be rotated in either direction without rotating the spindle or motor, or, if desired, the handle can rotate the spindle without rotating the motor or operate both at the same time. To rotate the motor-armature without current, the clutch member E is brought into engagement with the clutch member J by the foot-lever arrangement F, so that by the rotation of the handle when clutch members are engaged the gear becomes operative from the spindle to the armatureshaft, thereby enabling same to be rotated.

I do not limit myself to the arrangement and construction shown, as the same may be varied without departing from the spirit of my invention.
